In 1941 Switzerland issued two stamps to mark the 650th anniversary of Swiss independence. The design on the low value stamp includes a map of Lake Lucerne or the Lake of the Four Cantons, and the arms of Switzerland on the left, Schwyz on the upper right, and Uri, lower right. The device at the bottom center of the stamp has the arms of the Cantons of Obwalden on the left and that of Underwalden on the right.

     This league was the foundation of the Swiss Confederation which now includes twenty-two Cantons or states.
